8-Channel Video and Audio Quality Monitoring System


The true quality of digital television is monitored through the viewers' eyes. This is a low-cost, space-saving, ultimate edition of a multi-channel quality monitoring system for CATV and IPTV, which can monitor 8 HDTV/SDTV channels in real time.


Connect up to 8 digital TV STB to NP2000 using only AV cables and unacceptable quality (such as block errors, audio jumping, freezing, muting, blackouts) are detected by No Reference(NR) technology (quality evaluation is carried out only from the evaluation signal only, not using a reference signal). By using NP2000, it will be possible to manage the quality of experience (QoE) of the viewers for all service channels in real time, which leads to increased customer satisfaction, prevention of significant failures, and operational efficiency.

  • Block error detection by newly developed NR technology
  • Split screen output of 8 channels
  • Error information notification by SNMP Trap. (max 3 IP addresses)
  • Efficient operation by an application software for monitoring and control
  • Sensitivity can be set independently for each error detection by channel by channel
  • Immediate image pickup feature for error channel
  • Deployment in major MSOs in Japan
